With ample space for everyone and the Tagus river as a backdrop, this is a mostly flat course, with just a 1km climb (6% incline) before the turn around point at the middle of each lap.

Four laps out and back course will take you around the waterfront. There will be 2 aid stations at each lap, located at km 2 and 4. A total of 8 aid stations on the 21,1 km.




Where to watch on race day?

The swim takes place on an enclosed area, and you can walk alongside the athletes for the entire swim. Some parts you’ll be right on top of the action, others you’ll be a few meters away. If you’re not the walking type, the best spots to watch the swim are close to the restaurants next to the swim start, and next to the transition area, where the athletes will come out of the water. But you’ll have a great view of the swim pretty much anywhere around the swim venue.

On the bike spectators usually stay at the turn around point closest to the transition area, at the beginning of each lap, or some 200 meters up the road, at the start of and alongside Avenida D. João II.

On the run you can watch the athletes from one of the stands we have near the finish line, where you’ll get to watch the beginning of each lap and also cheer for every finisher. Alternatively you can go riverside and cheer from anywhere along the course.
